Your kidneys filter your blood, and remove excess fluid and waste from your body. Changes or damage to your kidneys may cause your kidneys to fail. Chronic conditions like diabetes and heart disease can cause kidney damage.
Chronic Kidney Disease (CKD) can progress over time to kidney failure. If your kidneys fail, your blood must be filtered (this is called dialysis treatments) several times a week. You may also need to have a kidney transplant.
Manage Chronic Kidney Disease risk factors
Approximately 1 in 3 adults with diabetes and 1 of 5 adults with high blood pressure may have CKD.
Other problems that put you at greater chance of kidney disease include:

1. Heart disease
2. High blood pressure
3. Overweight or obesity
4. Family history of Chronic Kidney Disease

Having CKD increases the chances of heart disease and stroke. Treatment can help prevent or delay cardiovascular death and kidney failure.
Early CKD has no signs or symptoms, so you may not know if you have it. The earlier you take action to prevent or delay kidney disease, the better.
If you’re at risk for CKD, get tested regularly. Ask your doctor how often is right for you.
If you have diabetes, get tested yearly.

Tips for healthy kidneys
– Take action to prevent, delay, or manage CKD
– Lose weight if you have overweight or obesity.
– Be active. Physical activity helps control blood sugar levels.
– If you smoke, quit as soon as possible.
– Take all of your medicines as prescribed.
– Stay in your target cholesterol range.
– Eat foods lower in salt.
– Eat more fruits and vegetables.
– Limit how much alcohol you drink. Alcohol can increase your risk of high blood pressure.
– Get your flu shot every year. People with CKD have a higher risk of severe illness from the flu.
